Please turn the power off, and allow the projector to cool down at least 20 minutes. After having conﬁrmed the following items, please turn the power ON again.

•Is there blockage of the air passage aperture?

•Is the air ﬁlter dirty?

•Does the peripheral temperature exceed 35°C?

•If the projector is used at an altitude of about 1600 m (5250

feet) or higher, set ALTITUDE of the SERVICE item in the OPTION menu to HIGH (57).
